Technical field
The present invention relates to a kind of method that inductive load is manipulated by pulsed and based on implementing methods described
Calculate unit and computer program.
Background technology
Bridgt circuit can for example in a motor vehicle be used for manipulate electromagnetism actuator, as example spray into formula injector or
Valve.For this purpose, bridgt circuit can have inductive load, the inductive load can be manipulated by multiple switch.These
The Part I of switch can be connected between the inductive load and high potential and form so-called flash branch road, and institute
The another part for stating switch then forms low side branch road between the inductive load and low potential.
For example, magnetic armature can be made to be transported from its resting position by manipulating the inductive load in formula injector is sprayed into
It is dynamic to come out and discharge the path for The fuel stream.Manipulated by pulsed the inductive load, namely by when clock
Each switch of the bridgt circuit is rapidly switched on and off to system, the magnetic armature desired position can be maintained at
In, so as to which fuel flow rate regulation is arrived into desired numerical value.
The content of the invention
Proposed according to the present invention：With independent patent claim it is feature, that sensing is manipulated for pulsed is negative
The method of load and computing unit and computer program for implementing methods described.Favourable design is that appurtenance will
The theme for description below of summing.
The inductive load can be by being connected the H bridges in other words of the bridgt circuit between first and second potential connector
Circuit is connect to manipulate.First high side switches be connected the first joint of the inductive load and first potential connector it
Between, the second high side switches are connected between the second joint of the inductive load and first potential connector.Described first
High side switches and the second high side switches especially correspondingly form so-called flash branch road.It is low to be opened when branch road is correspondingly low by first
Close and the second lower edge switch is constituted.First lower edge switch is connected the first joint and described second of the inductive load
Between potential connector, second lower edge switch be connected the second joint of the load and second potential connector it
Between.
First potential connector electrically connects with of a relatively high current potential, is for example electrically connected with service voltage in an advantageous manner
Connect, second potential connector is in an advantageous manner with relatively low current potential, especially with being electrically connected to ground.
As corresponding high side switches lower edge switch in other words, using single switch element or it can also can divide respectively
Shi Yong not multiple switch element, the switch element of different types of structure if necessary.As high side switches and lower edge switch, for example can
Enough use transistor, especially mosfet transistor（Metal-Oxide-Semiconductor Field-Effect
Transistor：Mos field effect transistor）Or IGBT（Insulated Gate Bipolar
Transistor：Insulated gate bipolar transistor）.
During the manipulation stage, first high side switches and second lower edge switch closure.In this case, it is electric
Stream can be between the potential connector through inductive load flowing.During the first unloaded stage, the first low side
Switch and second lower edge switch closure.In this case, electric current is through the inductive load and the low side branch road
Switch flowing.In the second unloaded stage, electric current flows through the inductive load and through the switch of the flash branch road.
During the second unloaded stage, first high side switches and second high side switches closure.Here, what remaining was not mentioned
Switch is in each stage（Manipulation stage and unloaded stage）In correspondingly disconnect.

Use structure identical control circuit driving switch circuit in other words.Thus achieve the flexible of the bridgt circuit and not
Complicated structure.
Advantageously, thyristor such as transistor, preferably MOSFET or IGBT are used as the first flash respectively
Switch is with the second high side switches and as the first lower edge switch and the second lower edge switch.Especially structure identical semiconductor is opened
Closing element is used for each described switch, and this realizes simple structure and effective manipulation to the inductive load.
It is preferred that manipulating the inductive load by pulsed to implement pulsewidth modulation.Advantageously, corresponding flash is opened
Close in other words lower edge switch by means respectively of pulsewidth modulation（PWM）To control.Thus enable in particular to targetedly adjust set through
The electric current of the inductive load.
According to a kind of advantageous embodiment, the inductive load is manipulated by pulsed to manipulate the member in motor vehicle
Part.The inductive load enables in particular to be arranged in corresponding element a part for the element in other words as coil.At this
In the case of kind, first potential connector for example can with the service voltage of carried on vehicle power network in other words with automotive battery
Electrical connection, and second potential connector can be with being electrically connected to ground.
Manipulation to corresponding actuator can be implemented by methods described with extremely simple and effective manner.With
It is extremely simple thus, it is possible to be designed in the bridgt circuit of automotive field, the load of each switch and for disconnecting/
Close the load of the corresponding control circuit of switch driving switch circuit in other words can be kept as it is relatively low.It is corresponding to perform
The danger --- this may cause the security risk of whole motor vehicle --- of the failure failure in other words of device can be reduced, thus
Avoid the maintenance of trouble and costliness.
Being manipulated preferably by means of the inductive load being capable of solenoid-operated actuator.By the manipulation of pulsed especially
Desired rated value is arrived into the physical parameter influenceed by the actuator regulation.Especially pass through arteries and veins during pulsewidth modulation
